E. coli in Nursery, Pounds of Pork in Grow-Finish: NOVUS Shares Swine Insights at ASAS Midwest

CHESTERFIELD, MO (February 26, 2026) – NOVUS will present new research highlighting nutrition strategies that support pig health and performance during the American Society of Animal Science (ASAS) Midwest meeting. Scientists will share findings that address profit-limiting challenges facing swine producers, including nursery and growing pig health, survivability, and feed efficiency.

“These studies show how targeted nutrition strategies can support pigs during periods of stress while also aligning with producer goals for efficiency and survivability,” says NOVUS Global Swine Research Manager Jesus Acosta, Ph.D. “Sharing this research at ASAS allows us to engage with nutritionists, veterinarians, and producers who are looking for practical, science-based solutions.”

Acosta’s presentation focuses on the role of protected benzoic acid in nursery pig diets. The research in two parts evaluated supplementation with NOVUS^® PB Feed Solution (a protected source of benzoic acid) under Escherichia coli F18 challenge conditions and in large scale commercial production settings. The objective was to understand how the protected gut health modulator influenced inflammatory markers, microbial populations, and overall pig performance during the critical nursery phase.

NOVUS Global Swine Lead Bradley V. Lawrence, Ph.D., will present work performed with NutriQuest that explores how mineral source, rather than total inclusion rate, matters for growth performance, health outcomes, and economic return in growing pigs. The findings reinforce the importance of selecting mineral sources that are accessible to the animal and aligned with modern production goals.

“When it comes to minerals, more is not necessarily better, depending on the source,” Lawrence says. “The data show this clearly with respect to the benefits of providing growing-finishing pigs fed methionine hydroxy analogue bis-chelates. The results show benefits in growth and pounds of pork going to a primary market, which ultimately result in improved profitability.”
